Procurement Notes

Verify the specific ordering suffix 'E' corresponds to the PDIP-16 through-hole package variant when sourcing. Confirm that the component meets RoHS requirements as indicated in distributor specifications. Ensure the procurement channel sources genuine Texas Instruments products to guarantee performance parameters such as the 129 ns propagation delay and 1.5 V to 5.5 V operating voltage are maintained. Cross-reference the manufacturer part number CD74AC112E with official datasheets to avoid confusion with surface-mount alternatives like the M96 variant.

Selection Notes

Select the CD74AC112E when a dual J-K flip-flop with negative-edge triggering is required for through-hole PCB designs. This component is suitable for applications needing differential outputs and broad input voltage compatibility with CMOS or LVTTL logic levels. Consider this part for systems requiring operation across a wide temperature range from -55°C to +125°C. It is appropriate for general-purpose digital logic applications where the AC series speed and power characteristics align with system requirements.

Part Context

The CD74AC112E belongs to the Texas Instruments 74AC logic family, which offers high-speed performance with low power consumption compared to earlier standards. As a dual flip-flop, it integrates two independent J-K toggle circuits into a single 16-pin DIP package. This component serves as a fundamental building block for sequential logic design, providing reliable state retention and transition capabilities in digital systems.
